+#  uopi test SoftIOC startup script
+#
+#  Prerequisites:
+#    • EPICS Base 3.15+ (for RNDM calc function)
+#    • 'softIoc' binary in PATH  (usually $EPICS_BASE/bin/$EPICS_HOST_ARCH/)
+#    • Optional: caput (from EPICS tools) to pre-fill UOPI:WAVEFORM
+#
+#  Usage:
+#    cd workspace/softioc
+#    ./st.cmd
+#
+#  Or directly (no waveform pre-fill):
+#    softIoc -s -d workspace/softioc/uopi_test.db
